48V90A 94% Compac DC Smart Power Supply Solution for Telecommunication Data Center

 

 

Product Overview of DC48V 90A Power System

 

The ET series rectifier is a DC48V 90A power system operating at 48V, engineered to ensure reliable power distribution for telecommunications infrastructure, data centers, and industrial applications where uninterrupted operation is critical. It operates from a 220V AC single-phase input and delivers a tightly regulated DC output ranging from –43V DC to –58V DC, with a nominal value of –53.5V DC. Achieving over 94% conversion efficiency even under full load, this system is ideal for energy-efficient, high-density installations.

Designed for Continuous Operation with Modular Flexibility
Engineered with redundancy in mind, the system supports up to three hot-swappable 1740W rectifier modules in an N+1 configuration. Each module weighs under 1.5 kg and utilizes forced-air cooling for consistent thermal management. With advanced power factor correction (≥0.99) and low total harmonic distortion (THDi ≤5%), it ensures clean output power while minimizing stress on upstream equipment. The unit is housed in a 2U, 19-inch rack-mountable chassis rated IP20, enabling front-access maintenance and convenient top-side cable routing.
